Studier av koppar i mjölk : en prooxidant med negativa effekter på mjölkkvaliteten
The taste of the dairy product is probably the main factor determining consumer?s dairy products choice. Consequently it is of great importance that the product tastes good and as expected every time. Off-flavors in milk can be caused by for example oxidation of the milk fat. Since copper is a prooxidant, a high copper content in the milk can cause oxidation.
Den relativa viktens (kalv/ko) inflytande på kalvningsegenskaperna hos SRB och SLB :
Difficult calvings and stillbirths are problems in Swedish dairy production that result in large expenses for the farmers and welfare issues concerning the animals. A common opinion is that the live weight of SRB and SLB is increasing, and whether increased weights have caused the increase in calving problems has been discussed. The aim of this study was to investigate the relationship between the relative birth weight (calf/cow) and calving difficulty and stillbirth, respectively. The importance of breed and parity for the relative weight has been investigated, and comparisons with previous studies have been made to evaluate whether the relative weight has changed over the last decades or not.
The study was based on 807 calvings, registered during the period 1993-2003 in the experimental dairy herd of the Swedish University of Agricultural Sciences (Jälla).
Effekter av spädningsvätska på motilitet och fertilitet hos hingstsperma : en jämförelse av subjektiv motilitetsbedömning och QualispermTM
At SLU, Divison of Reproduction, Dept of Clinical Science, there is an ongoing project on the development and evaluation of new methods for the assessment of stallion semen quality. This EEF-study, which is a part of that larger project, has focused on the effects on motility and fertility of stallion semen of two different extenders and selection. Both an objective method and a subjective method for analysis have been used and compared in the study.
The increase in the use of artificial insemination with cooled semen in Swedish horse breeding over the last decade is thought to play a part in declining foaling rates (Kareskoski et al, 2006, Kuisma et al, 2006). This calls for better evaluation methods of semen quality since cooling and transportation put higher demands on semen quality in order to maintain fertility (Aurich, 2005).

Samband mellan överlevnad, tillväxt och pälskvalitet hos lammen och fruktsamhet och modersegenskaper hos tackan
There are several factors influencing the profitability of production with sheep. Two of the most important factors are ewe fertility and lamb survival. Also growth capacity of the lambs is important. This paper aims to review correlations between the ewe?s fertility and maternal behavior and lamb survival.
En komparativ studie av fem rankningsalgoritmer för query expansion
The purpose of this thesis is to compare five different ranking algorithms for query expansion. The algorithms compared are f4, f4mod, porter, wpq, and emim. This is done using a TREC collection, a selection of topics, and relevance judgements. Relative recall is measured before and after the expansion of the query. The study shows that all of the algorithms manage to increase the relative recall, f4 being the one most successful..

Extrem hundavel : ett välfärdsproblem för dagens rashundar
For centuries inbreeding has been used to refine traits in dogs, making desired traits more hereditary and thereby, different breeds have been invented. Breed standards have been written for each of these breeds, describing in detail the different characteristics of each breed. When humans start to choose which animal to breed from, so called artificial selection, taste is put before function and the laws of nature, the natural selection, cease to apply. During this development, pedigree dogs have gone towards more and more extreme exterior characteristics and the dogs may have inherited various, more or less, severe problems for example compromised vision, impaired ability to move and difficulties to breathe. However they can still survive and reproduce because humans provide them with the conditions to do so.

The purpose of our essay is to investigate the trust in accountants. The method we used to investigate the trust was a survey and a questionnaire was used to collect the data. The data was gathered from three different groups, shareholders, lenders and tax authority. When we analysed the data we found out that the groups trust in accountants were neither strong nor weak. The results can be generalized on all the three groups because the observations were scattered around the means and we used random selection to collect the data.
Cystocentes versus spontankastad urin : tillförlitlighet vid klinisk diagnostik hos tik
This master thesis was conducted in order to investigate the effects of the browsing
species Yeheb on animal tissues in Swedish landrace goats and to make a literature
review in order to increase the knowledge of the importance of this plant for livestock
production in Somalia. The evergreen Yeheb bush is a very important feeding source for
grazing and browsing animals in Somalia during the dry period. Yeheb contains
cordeauxiaquinone that stains the bones of the animals red/pink, which has been an
increasing problem when exporting meat to foreign countries. In an experiment, two
goats were fed dry and fresh leaves from the Yeheb bush for one and two months,
respectively. The goats did not feed the intended amount of dry leaves, since the supply
and palatability was not as high as estimated.

Mountain holding in the 21st century ? difficulties and possibilities This study examines the difficulties and possibilities that mountain holding farmers have today. The following questions were considered: i) Who is cultivating mountain holdings today? ii) Which is the most important reason to keep animals there? iii) What kind of subsidies are most common? iv) What kinds of animals and what breeds are the most common? v) For how long period of time are the animals kept at the mountain holdings every season? vi) How are the fundamental regulations in the animal welfare law being followed, and are there any problems/conflicts in keeping animals at the mountain holdings? vii) What meaning do the animals have for the farmers and what are the farmer?s thoughts about the future? A survey based on these issues was sent out to 107 mountain holdings farmers with animals on grazing land, where 59 % submitted a response. The results showed that knowledge on how to keep animals at the mountain holdings was overall good.
Estimation of reindeer lichen biomass by image analysis
During consultation procedures between forest owners and the Sámi, data on, e.g., reindeer lichen biomass on the current site is needed. Hitherto, the existing methods of measuring lichen cover and biomass has been either objective methods such as the Point Intercept method, which is time consuming, or some sort of subjective visual estimation, which is faster but less accurate. However, both these methods are sensitive to different observers and/or to different inventories. This paper addresses the further development and evaluation of a photographical inventory method that uses colour distribution in images to estimate lichen biomass. During the autumn of 2011 six different locations, with different grazing pressure and lichen cover, in Norrbotten county were inventoried using both the Point Intercept method and the photographical method, complemented with collection of biomass samples.
EU-stöd inom fårproduktion på Öland jämfört med Småland/fastlandet :
The Sheep is the oldest livestock, and has been in Sweden for 4-5000 years. Thanks to that you can obtain skin, as well wool and meat. Therefore it was an important animal. Sheep production has increased, strongly lately due to the pasture support.
The purpose of this paper is to find out what kind of different EU-subsidies you can get and to compare the subsidies in Öland and the main land.
Sheeps are very good conservationist with grass, bushes and herbs, because of different grazing lands hardness and growth is it important to control the pasturage strain. A good way to regulate this is to have different enclosed pasture to switch between.
I have been studying the different EU-subsidies.
Jewellery in the logic dreams - på jakt efter drömkänslan i konsten
Nina Johansson starts her essay by making some examples of dreams to show the diversity of the ?dream world?. She speaks of how all humans dream, that it ties us together. She wants to translate the ?feeling of dreams? into wearable objects, and to be able to do that, she must try and describe what that feeling consists of.
